فَتَوَلَّ عَنْهُمْ يَوْمَ يَدْعُ الدَّاعِ إِلَى شَيْءٍ نُّكُرٍ
[54:6]
So turn (your) back on them (for) the day when the inviter shall invite them to a hard task,
Therefore, (O Prophet,) turn away from them. The Day that the Caller will call (them) to a terrible affair,
So withdraw from them (O Muhammad) on the day when the Summoner summoneth unto a painful thing.
